i love the idea of them meeting on some message board as awkard little teens! i see he draws so it's probably safe to assume he loves art? could have been something like that or even music related if he cares about that at all! she's pretty much useless when it comes to saving money and holding down a job but for nico she would have saved money a few times just to see him. maybe she went out to new york three or four times before he officially moved?
